Use 2K buffers for IO to help achieve full device speed, rather than the
default wMaxPacketSize (64 or 512 bytes). This actually helps older FTDI
devices (which were USB 1/full speed) more than the new H-series high
speed, but even for the new chips it helps cut the number of interrupts
when doing very high speed (3-12mbaud).
